Leviticus 21:21-23

New Catholic Bible

²¹ No descendant of Aaron the priest who has a defect shall draw near to present offerings made by fire to the Lord. He who has a blemish shall not come to offer the bread of his God ²² for the bread of his God is most holy. He can eat what is holy, ²³ but he shall not enter inside the veil^[a] or approach the altar because of his defect, lest he defile the sanctuary. I am the Lord, who makes them holy.’ ”
